fetch https://9front.org/iso/9front-11250.amd64.iso.gz
gzcat < 9front-11250.amd64.iso.gz > 9front.iso
truncate -s 8G 9front.img

Normally:
Once you connect vnc to its port (:5900), it should boot up in 9front from the
iso itself and then you can do an install on the disk by following directions.

What happens is it dies even before 9front is started.
